ABSTRACT

A ecodopplercardiografia permanece como o exame de eleição para o diagnóstico e acompanhamento de pacientes com estenose aórtica. Contudo, existem circunstâncias que dificultam a realização desse exame e podem fazer com que seus resultados sejam insuficientes. Nessas situações, muitas vezes lança-se mão do cateterismo cardíaco, mas a ressonância magnética e a tomografia computadorizada podem ser utilizadas para explorar esses pacientes de forma não-invasiva. A ressonância magnética permite realizar a planimetria da área valvar e também explorar a anatomia e a função cardíaca, mostrando boa correlação com os dados dos estudos angiográficos. Já a tomografia tem sido utilizada para estimar o grau de estenose valvar a partir do cálculo do índice de calcificação valvar, uma vez que vários trabalhos têm apontado no sentido de que há íntima relação entre esses dois fatores.

ABSTRACT

The proper management of aneurysms of the aorta and of aortic dissection requires the precise evaluation of the target vessel. It is important to have a correct definition of the artery diameter and the full extent of the diseased segment. Besides it is also mandatory to have an exact appreciation of the morphology of the vessel and the relation of the affected segments and the branches of the aorta. In case of dissection it is also important to have information on the left ventricular function, the aortic valve function and the presence of pericardial or pleural effusion. Computed tomography and magnetic resonance imaging are non-invasive imaging modalities that may be used to evaluate the aorta and define the diagnosis. Recent technological developments made the results of both methods similar in many instances, making the selection between them confusing. The goal of this paper is to review the relative contribution of each of these powerful techniques, trying to help the physician in selecting the most adequate test for each particular patient.
